Page 1 of 2

Chapter 3


3.1 General advises CAUTION

• •

• • • • • •

Eccentric reducer

Install the pump with the suction branch in axial and the discharge branch in vertically upward position. The pipes should have at least the nominal diameter of the pump branches. Where this is not possible, it should be ensured that the flow velocity in the suction or feed line does not exceed 2 - 3 m/s. Flange seals must not protrude towards the inside. Clean the pipework prior to pump installation.

If the liquid is contaminated, a filter should be fitted upstream of the pump whose filter area should be three times the pipe cross-sectional area (about 100 meshes/cm²). The suction opening of the suction line should be well below the liquid level, and a strainer should be used. The strainer must be far enough from the bottom to avoid excessive inlet losses which could impair the pumping performance. It is advisable to check that there is no leakage.

Support the pipelines so as to prevent distortion of pump components. Avoid rough cross-section transitions and sharp bends. Eccentric reducers must be used in the event of different nominal diameters. In the event of unfavourable suction conditions, steady flow should be ensured over a length of 15 x suction branch diameter upstream of the suction branch.

3.2 Suction or feed line

Pump installation

A suction line must rise to the pump and a feed line must slope gradually downward towards the pump.

A shut-off valve should be installed in the feed line, it will be closed for maintenance work. It should be installed such that air pockets cannot form in the spindle cap, i.e. with the spindle in a horizontal position or pointing vertically downward.

3.3 Vacuum equalising pipe

Feed operation, suction operation Reducers mounted between suction branch and suction/feed line must be eccentric to eliminate the possibility of air pockets being formed.


If the pump draws from a system or tank under vacuum, an equalising pipe must be installed connecting the highest point of the suction line to the gas chamber of the suction tank to prevent gas bubbles that may be carried by the flow from entering the pump. The line should be fitted with a shut-off valve which will be closed for maintenance on the pump.




Page 2 of 2

Chapter 3

Vacuum operation

3.4 Discharge line The run of the discharge line must be steep. In order to adjust the desired duty point, a regulating valve must be fitted in the discharge line downstream of the pump. If a check valve is used it should not close abruptly and be able to cushion pulsations.

3.5 Pressure monitoring In order to monitor the pressures upstream and downstream of the pump, the installation of measuring points in the pipeline is recommended.

3.6 Electrical connections The electrical connection for the driving motor must comply with the relevant local rules and requirements (ELexV, EVU-standards, directive 94/4 EC).

Chapter 4

Unpacking, handling

4.1 General advises

• • • • •

Do not lift heavy equipment overhead of personnel. Lifting the pump

A safe distance must be kept when lifting and moving the equipment. Use only approved and suitable lifting equipment. The length of the lifting equipment should be such that the pump or the set are lifted in horizontal position. Do not attempt to lift the pump or the pump set using eyebolts on pump components. CAUTION

•

Do not remove protection covers from the pump branches, as they prevent contamination of the pump. Lifting the pump set

4.2 Unpacking Do not unpack the pump until it has been carefully checked for damage that may have occurred in transit. Report any damage on the counterfoil or delivery note. Claims must be made immediately on the carrier or the transport insurance.

4.3 Intermediate storage If the pump or the pump set is not to be installed immediately it should be stored in a dry and vibration-free room. The packing should be checked for damage on a monthly basis.

4.5.1 Removal of preservation In general, a preservation coating is only applied to SG iron pumps. To remove the preservative coating, the pump should be filled and drained several times using appropriate agents, e.g. solvent naphta, diesel oil, or an alkaline detergent. Flush with water, if necessary. The pump must be installed and put into operation immediately afterwards. 4.5.2 Re-preservation If the pump has been supplied preserved and is to be stored, a new preservative coating should be applied after six months.

4.4 Transport The pump or the pump set must be lifted as shown below:


4.5 Preservation

For suitable preservatives, contact Sterling SIHI.



Mounting of the pump

Page 1 of 3

Chapter 5

Clear and easy access to the shut-off and regulating valves and the measuring instruments must be ensured.


5.1 General advises

5.2.4 Installation position CBSD/CBHD pumps are installed in horizontal position.

• • • • •

The foundation of the pump must be level and have a minimum of vibration. It is recommended to use a baseplate. Concerning the pipework, the pump must not be considered as a fixpoint. Care should be taken that the pipework forces and moments acting on the pump branches do not exceed the permissible pump branch loads acc. to ISO 5199. The pump must be properly aligned

5.2.5 Preparatory checks The following checks should be made prior to installation: − ease of running (check that the shaft is free to rotate by hand) − direction of rotation of the motor − shut-off valve in the suction or feed line and regulating valve in the discharge line must be closed − power to the equipment must be disconnected

The pipework must be properly installed. 5.2.6 Alignment of the pump set

•

•

Incorrect pump installation or alignment will lead to an overload on the machine which could be hazardous to personnel and environment if the pump is operated in a potentially explosive atmosphere. Leakage due to improper pipe or supply line connections may lead to the formation of explosive mixtures and be hazardous to the personnel and the environment if the pump is operated in a potentially explosive atmosphere.

After aligning the set the axial clearance between the two coupling halves measured at one point of the coupling must be the same over the complete circumference of the coupling, the permissible tolerance being ± 0.05 mm. Carry out the radial alignment of the coupling using a bevelled straight edge and a feeler gauge.

5.2 Prerequisites 5.2.1 Fitting tools Standard tools and lifting equipment are used. These should be available at the customer's end.

Aligning the coupling clearance

5.2.2 Permissible environment 5.3 Foundation The ambient temperature range should be from 20 °C to +60 °C (for restrictions see also chapter 2). The atmospheric humidity should be low in order to avoid corrosion. 5.2.3 Space utilisation The space required by the pump or the pump set can be seen from the attached table of dimensions or the arrangement drawing.


5.3.1 Placing the pump set Prior to placing the pump set on the foundation which should be well set, the following preparatory work must be carried out: − − − − −

check the dimensions of the foundation roughen and clean foundation surface remove shuttering/cores from the anchor holes blow the anchor holes clean check the positions and dimensions of the anchor holes against the arrangement drawing




Page 2 of 3

Chapter 5

The complete set mounted on the baseplate must be placed on the foundation with its foundation bolts suspended.

5.5 Accessories pipework

− Place shims under the baseplate on both sides of the foundation bolts, 10 mm from the baseplate edge − Use a spirit level to align the set − If necessary, place shims between the foundation bolts to prevent the baseplate from sagging. Care should be taken to minimise distortion of the baseplate during installation − The foundation bolts should be embedded in concrete using quick-setting grout − Tighten the nuts of the foundation bolts crosswise (when the grout is set) − Re-check the alignment with a spirit level

If the pump is equipped with a stuffing box or a double-acting mechanical seal in tandem arrangement, the shaft seal chamber needs to be flushed with liquid from an external source (connections on casing cover and seal gland are available). If the pump is equipped with a double-acting mechanical seal in back-to-back arrangement, the shaft seal chamber needs to be sealed with liquid from an external source (connections on casing cover and seal gland are available).

CAUTION

• •

Care should be taken at every check that the axial play of the pump rotor is taken into consideration. Avoid distortions when finally tightening the bolts.

5.3.2 Grouting the baseplate Prior to grouting the baseplate, carry out the following preparatory work: − Check the dimensions with regard to height and adjustment of flanges − Re-adjust baseplate, if necessary Ram earth-humid concrete under the baseplate or add shrinkage-free grout until the entire space under the baseplate is filled. Grouting should be a continuous process so as to ensure that no air pockets are left. When the grout is set re-tighten the foundation bolts and re-check the alignment of the coupling.

5.4 Pump installation in the piping system − Remove the protection covers from the pump flanges and the auxiliary pipeline connections − Correctly insert the flange seals − Connect the suction or feed line − Connect the discharge line

5.5.1 Shaft sealing

The sealing or flushing liquid must be free of solid particles, it should not crystallise and it must be compatible with the liquid handled. Water which is free from lime, oils having a maximum viscosity of 12 cSt at 50 °C or water-glysantine mixtures (max. glysantine content: 50 %) are possible sealing liquids. The sealing pressure should be at least 2 bar above the pressure prevailing in front of the mechanical seal (which is nearly equivalent to the pump suction pressure). The mechanical seal can be sealed by means of a thermosiphon sealing pressure unit - i.e. in a closed circuit - or by liquid flow, for example tap water. Thermosiphon sealing pressure unit The difference in height between the sealing liquid outlet on the mechanical seal and the thermosiphon inlet should be about 0,7 m. Air pockets should be avoided; therefore, the suction line, when operating under suction pressure, must have a gradual slope and the return line a gradual rise. Once the sealing pressure container is filled with the sealing fluid, a gas volume (compressed air or nitrogen) must be added to the sealing fluid. Using the flow principle to seal the mechanical seal If the mechanical seal is sealed using a liquid flow, control valves must be installed at the inlet and outlet of the liquid lines and a pressure gauge must be installed upstream from the point where the supply line enters the shaft seal chamber. The control valves are to be used to control the supply pressure for the sealing liquid and the pressure in the shaft seal chamber. 5.5.2 Intensive cooling If the pump is equipped with an intensive cooling bush (see picture below), a cooling liquid supply





Page 3 of 3

is required (connections on casing cover are available).

5.6 Hydrostatic test

• • Intensive cooling The following chart shows the cooling water requirement of the intensive cooling unit:

Chapter 5

For the hydrostatic test of pressure containing pump parts (casing, casing cover), a maximum pressure of 1.5 x nominal pump pressure should be applied. If the piping system is to undergo a hydrostatic test, the pump must be excluded from such testing.

6.1 General advises

6.3 Checks before first start-up

• •

• •

•

•

•

•

Observe the pump operating limits documented by Sterling SIHI (if there is any doubt, please contact Sterling SIHI). Safety measures should be taken at the customer's end to ensure (for example by means of a relief valve) that the permissible pump casing pressure is not exceeded during operation. If the liquid handled is hot, the pump must be filled slowly so as to avoid distortions or heat shocks. The flowrate must be changed at constant speed only on the discharge side. During operation the shut-off valve in the suction or feed line should always be kept open, in order not to run the risk of cavitation. Do not run the pump with the regulating valve closed for more than thirteen seconds, if there is no bypass line (for restrictions, see also annex).

The operator is to ensure the permissible maximum temperature of the liquid handled as a function of the temperature class is not exceeded. Specific limitations or restrictions resulting from pump design or mode of operation must be taken into consideration (see annex). Otherwise temperatures in excess of the temperature of the pumped liquid may occur on the pump casing which could be hazardous to personnel and environment if the pump is operated in a potentially explosive atmosphere. The operator is to ensure that a dry operation of the mechanical seal is prevented. Pumps equipped with a single-acting mechanical seal are only allowed to be operated when primed. For pumps equipped with double-acting mechanical seal, also the seal chamber must be flushed or sealed. The direction of rotation of the motor is only allowed to be checked with the pump primed (for pumps with single-acting mechanical seal) and, also, with flushed or sealed seal chamber (for double-acting mechanical seal).


− Are the pipelines connected and are the flange connections tight? − Is the pump incl. the pipework correctly primed? − Is the shut-off valve in the suction or feed line fully open? − Is the regulating valve in the discharge line closed or slightly open? − Is the motor ready? − Is the direction of rotation of the motor correct (check by momentarily switching on the motor)? − Is the coupling correctly aligned (see chapter 5)? − Has the shaft seal been installed? − Are the supply lines, if any, to the shaft seal open? − In the case of oil lubrication: has the bearing housing been correctly filled with oil?

6.4 Starting procedure − Check everything using the check list of subsection 6.3 − Switch on the supply systems of mechanical seal − Switch on the motor − Check the pressure gauges at the pressure measuring points − Open the discharge side regulating valve to adjust the duty point of the pump

6.5 Operation 6.5.1 Switching frequency For a start with the regulating valve closed or slightly opened and for uniform start-stop intervals, the following numbers of switching actuations apply: P kW < 12 12 < P <100 >100

Chapter 6

6.5.2 Operating range 0,3 Qopt < Q < 1,1 Qopt (continuos operation) 0,1 Qopt < Q < 1,3 Qopt (short-term operation) This operating range is applicable if waterlike liquids are pumped. If liquids having distinctly different physical properties are handled, it may be necessary to narrow the permissible operating range (see annex). 6.5.3 Alignment The alignment of the set should be re-checked at operating temperature (see 5.2.6). Re-align the set, if necessary.

6.6 Stopping procedure − close the discharge side regulating valve − switch off the pump − switch off the supply systems of mechanical seal − when the pump is at a standstill, close all other shut-off valves If there is danger of freezing, the pump should be drained down.

• •

Please note that there will always be some residual liquid even if the pump is turned upside down. Ensure that the pump does not contain any hazardous substances when it is returned to the manufacturer's factory. CAUTION

• •

Ensure that the pump is preserved during prolonged inactivity. For inactive pumps, the mechanical seal and the rotor risk to get stuck. Pump rotor should therefore be turned by hand every 3 weeks to restore the rotor’s smooth motion.

Chapter 7

7.2 Maintenance and inspection 7.2.1 Grease lubricated bearings

7.1 General advises

• • • •

•

•

•

•

The pumps supplied are equipped with a greaselubricated pump side rolling contact bearing and a grease-lubricated driver side rolling contact bearing, which should be re-greased in accordance with the following table.

Flush the pump thoroughly before disassembly to purge away the residual liquid left after draining the pump. Ensure that people and the environment are not put at risk through explosive, toxic, hot, crystalline, or acid liquids handled. The workplace for disassembly or assembly must be clean. Ensure trouble-free bearing performance, for example by regular inspection of bearing temperature or vibration behaviour. The bearing temperature must not exceed 80°C, if oil-lubricated, or 90°C, if grease-lubricated. Bearing operation must be free from vibrations. Heat exchange between the bearing housing and the environment must not be impaired, insulation is not permissible. Inspect the mechanical seal leakage at regular intervals, e.g. by visual inspection. An amount of a few cm³ per hour in the form of vapour, mist or drops is permissible.

Assembly and disassembly of this pump must only be performed by authorised and qualified personnel who have adequately familiarised themselves with the subject matter by studying this manual in detail. Otherwise the pump could be damaged and people and the environment can be put on risk if the pump is operated in a potentially explosive atmosphere.

light duty

normal and heavy duty

n ≤ 1500 rpm every 5000 hours

n > 1500 rpm every 2500 hours

If the pump is operating in a harsh (e.g. dusty or hot) environment the greasing intervals should be considerably shorter. Only high quality anticorrosive lithium soap base grease containing no resins or acids should be used, e.g. K3K to DIN 51825. After 17500 operating hours or 2 years the rolling contact bearings should be replaced. 7.2.2 Oil lubricated bearings The pumps are supplied without oil in the bearing housing. Before first start up, the bearing housing must be filled with oil. − Take oil bottle out of the screw-in elbow − Fill the bearing housing with oil until the oil becomes visible in the screw-in elbow − Fill oil bottle through the filling tube − Re-connect oil bottle; as long as there is oil in the bottle the oil level in the bearing housing is sufficient

Anti-friction bearings which are old or improperly lubricated may cause the machine temperature to increase and be hazardous to personnel and environment if the pump is operated in a potentially explosive atmosphere. Leakage from a pump equipped with a singleacting mechanical seal may lead to the formation of explosive mixtures and be hazardous to personnel and environment if the pump is operated in a potentially explosive atmosphere.

Chapter 7

Pumps with packing: The cross-section of the packing (yard ware) to be used should be 0,3 to 0,6 mm smaller than the packing chamber. Calibrating it to a dimension smaller than specified (by means of a packing press) is not recommended as the original packing size will be restored when the packing is inserted in the housing cover. The packing cuts should be straight. To achieve a tight and parallel contact of the cut packing ring ends, the cutting angle on both ends should be about 20° (see sketch). The mean packing ring length is calculated using the following equation:

  D − d L M = d +   ⋅ 1,07 ⋅ π  2    L M : mean packing ring length d: D:

diameter shaft sleeve diameter stuffing box

− Slide the stuffing box gland and the shaft sleeve over the shaft. Fasten bearing housing assembly to the casing cover − Insert each ring separately, cut ends first, using a split sleeve or the packing gland; pull the ends of the rings laterally apart and push the rings over the shaft sleeve into the stuffing box. Joints in succeeding rings should be staggered 7.6.3 Adjusting the rotor on pumps semi-open impeller

with

The clearance between the impeller blades and the volute casing is central to the operating safety and the efficiency of the pump. The clearance is factory-adjusted and must be readjusted after each pump disassembly. The rotor position is determined by the drive side rolling contact bearing, 32.11, in the bearing cover, 38.20. It can be changed as follows:




Page 6 of 6

Chapter 7

Pulling the rotor towards the drive side: − Release cheese-head screws, 91.44 − Tighten set screw, 90.81 Pushing the rotor towards the pump side: − Release set screw, 90.81 − Tighten hexagon cheese-head screws, 91.44, until set screw is seated against the bearing housing.

Axial rotor adjustment Adjust the required clearance between impeller and volute casing as follows: − Adjust clearance between impeller and volute casing to 0,3, before fastening the back pullout assembly in the volute casing and installing the mechanical seal − Install gasket, 40.00, in the volute casing and bolt the back pull-out assembly to the volute casing − Check that the rotor turns freely − Move the rotor as described towards the pump side until the impeller abuts against the volute casing − Measure clearance A between the bearing bush and the bearing housing, using a feeler gauge − Move the rotor by 0,3 mm towards the coupling side; check at the clearance between bearing bush and bearing housing − Tighten cheese-head screws, 91.44 − Adjust and tighten mechanical seal according to the mechanical seal installation instructions

7.6 Inspection After assembly, proceed as follows: − Check that pump is easy to rotate and leakproof − Check that the axial clearance of the shaft assembly is within the permissible range (0,15 mm – 0,3 mm) In addition, we recommend that a leak test with air be carried out.

Annex

Max. permissible temperature of pumping liquid The highest temperatures usually occur on the pump casing surface, on the bearing housing in the area of the anti-friction bearings and on the casing cover near the mechanical seal. The temperature occurring on the pump casing is almost the same as that of the liquid handled. A maximum temperature of 80 °C, if oil-lubricated, or 90 °C, if grease-lubricated, can be expected in the area of the anti-friction bearings, provided the requirements for appropriate pump operation are met and regular maintenance on the bearings is provided. Insulation of the bearing housing is not permissible. If the pump is adequately filled with liquid, the temperature of the liquid handled in the shaft seal area should not increase by more than 15 °K for dead end operation with a single-acting mechanical seal. With double-acting mechanical seals the temperature rise depends largely on the flushing or sealing liquid (if there is any doubt, please contact Sterling SIHI). Thus, the following theoretical maximum temperature of the liquid handled as a function of the temperature class according to prEN 13463-1 is obtained. The maximum operating temperature of the pump (see chapter 9) and the operating limits of the mechanical seal must be observed (if there is any doubt, please contact Sterling SIHI or the mechanical seal manufacturer). Temperature class Max. temperature of acc. prEN 13463-1 pumping liquid T5 85 °C1) T4 120 °C T3 185 °C T2 285 °C T1 350 °C 1) Only with oil lubrication

Temperature rise of the liquid handled caused by internal losses Disregarding the mechanical losses of the anti-friction bearings and the mechanical seal and the dissipation of heat through thermal radiation and conduction, the rise in temperature at a given flowrate is calculated using the following equation:

∆T = 3,6 ⋅

P η ρ Q c

P(1 − η) in °K ρ⋅ Q⋅ c

Pump power in kW Pump efficiency Specific gravity of pumping liquid in kg/dm³ Capacity in m³/h specific heat capacity of pumping liquid in kJ/kgK

Temperature rise of the liquid handled in the case of operation with the regulating valve closed If the pump is operated with the regulating valve closed the theoretical rise in temperature is infinite. In this case, the rise in temperature per second of the liquid handled is calculated using the following equation:

∆T P in °K/s = t ρ⋅ V ⋅c
